Description: Defines SNMP notification objects for Avaya/Nortel BayStack ERS switch hardware and protocol events.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is BAY-STACK-NOTIFICATIONS-MIB?

BAY-STACK-NOTIFICATIONS-MIB is an Avaya/Nortel private MIB defining SNMP trap/notification objects for the BayStack and Ethernet Routing Switch (ERS) product families, covering security, stacking, and licensing events. It exposes variable bindings carried in traps rather than a polled table of ongoing metrics, including EAP (802.1X) access-violation MAC addresses, login-failure details, stack-size information, and trial license expiration data. For hardware/software status monitoring it is particularly valuable for fault and security event detection: it reports failed login attempts (with username/address), 802.1X authentication or user-based-policy failures on specific interfaces, unexpected stack-size changes, forced stack mode transitions, and looming trial license expirations that could affect device functionality. It depends on the broader BayStack/ERS switch MIB family for the objects and context surrounding these notifications, and follows standard SNMPv2 notification conventions. It is deployed on Avaya/Nortel BayStack and ERS stackable switches in enterprise LAN environments, particularly where switch stacking and 802.1X port security are in use. Engineers can download the BAY-STACK-NOTIFICATIONS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in BAY-STACK-NOTIFICATIONS-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • Avaya/Nortel BayStack switch
  • Avaya/Nortel Ethernet Routing Switch (ERS)

Monitoring Examples

A monitoring system would subscribe to traps carrying bsnLoginFailureUsername, bsnLoginFailureAddress, and bsnLoginFailureType to alert on repeated failed management logins, potentially indicating a brute-force attempt. A trap containing bsnEapUbpFailureIfIndex and bsnEapUbpFailureMacAddress would flag a specific switch port and client MAC that failed 802.1X user-based-policy authentication. Separately, bsnActualStackSize changing unexpectedly, or a bsnEnteredForcedStackModeMAC notification firing, would alert an admin that a switch stack has lost or gained a unit, while bsnTrialLicenseExpirationTime nearing zero would warn of an imminent loss of licensed features.

What Can Be Monitored

  • login failure events (user/address/type)
  • 802.1X/EAP authentication and access-violation events
  • stack size changes and forced stack mode
  • trial license expiration
